Handheld Devices as a Learning Aid
A handheld device is any device that can be used on the go and which is small enough to be kept in a pocket. They usually function as miniature computers and are equipped with a range of functions, including maintaining schedules, databases for storing names and other contact information, like phone numbers and addresses. In addition, handheld devices such as mobile phones can perform calculations, take notes and connect to the Internet via a modem or by using various wireless connectivity technologies, including WAP, Wi-Fi and Bluetooth.
A design challenge facing these products is data input. This is because the keyboard is very small and models that feature hand typing are not very user friendly. The development of touch-screen technology, whereby a stylus is used to input data, has gone a long way to address this problem. This, together with the introduction of 3G technology, which allows for mobile broadband, has made handheld devices suitable for use as teaching aids.
Most handheld or PDA’s, share the same operating system, known as Palm OS. Palm OS is a free software, which can be downloaded from the Internet. For example, it allows students to use their handheld to perform various specific tasks. Some of the tasks that can be accomplished include drawing graphs, word processing and carrying out research, by browsing the Internet.
For teachers, handheld devices can be used for record keeping, scheduling and teaching applications. In addition the devices are equipped with other tools, like digital recorders, cameras and GPS devices, which can be useful during field trips.
